Takealot garanteed delivery is a joke

It's sad to do this as I have been a loyal supporter since their start, but of late their service has been terrible. It's now the second time in a row I have paid for a garrantee on delivery time and they on this order are 2 days late, no notification of why not any updates I had to call 8 times only to find out that what they said was in stock was not so now I'm inconvenienced and am really disappointed with them. The first order was late by a funny 24 hours this second one seems to be going for 3 times that amount in time being late. This is useless and it does not help calling then as it does nothing to help.
